Central New Brunswick Snowmobile Trail Report for Trail #42 near Doaktown . The Miramichi Sno-Goers Groomer is back in service today . See here heading north on Trail 42 at McNamee , returning to south to McGivney then back to Serpentine tomorrow . Trail 42 from Fredericton to Doaktown and 58 to Serpentine should be superb with the severe cold weather to help freeze it up . Warmer temps are forecast for this weekend so it will be a good day to take advantage of the Ski-Doo Demo ride sponsored by Torque Motorsports at Wilson’s on Saturday .
